Answer:
Step-by-step explanation:
Y=1
Explanation:
You have to plug 2+x into the y of the first equation. After you solve that you should get-1 as the answer for x so you plug -1 into the x of the second equation and the value of y would be 1.
1 inch = 2.54 cm
3 inches = 3 * 2.54 = 7.62 cm
<span>The measure of angle dcb is 120</span>°.<span>
Because in a parallelogram, Consecutive angles are supplementary that means (D + C = 180°).
given that angle adc is equal to 60</span>°
So, ∠adc + ∠dcb = 180°
60 ° + ∠dcb = 180°
∠dcb = 180 - 60 = 120°
Thus, the measure of angle dcb is 120°.
